烟台市成品及散装食用油中塑化剂含量的调查
目的 了解烟台市售成品及散装食用油中塑化剂的迁移情况。方法 样品前处理依据GB/T 21911-2008, 乙酸乙酯: 环己烷(1:1, V:V)提取, 凝胶渗透色谱装置净化, 三重串联四级杆气质联用仪进行定性及定量分析。结果 成品油中塑化剂有少量检出, 而散装油的检出率很高, 主要为邻苯二甲酸二(2-乙基)己酯(DEHP)70%、邻苯二甲酸二丁酯(DBP)60%、邻苯二甲酸二异丁酯(DIBP)45%和邻苯二甲酸二异壬酯(DINP)20%, 超标率为DEHP 35.7%, DBP 58.3%。结论 市民在购买食用油时应尽量购买成品油, 购买散装的食用油时尽量不要使用非食品级的塑料桶盛放。
Objective To investigate the migration of plasticizers from plastic packaging into finished and bulk oil in Yantai. Methods According to GB/T 21911-2008, the samples were extracted with ethyl acetate: cyclohexane (1:1, V:V), and purified with gel permeation chromatography. Gas chromatography-tandem mass spectrometry (GC-MS/MS) was used for qualitative and quantitative analysis. Results There were low detection rates of plasticizers in finished oils, but high rates in bulk oils. The detection rates of bis(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP) and diisononyl phthalate (DINP) were 70%, 60%, 45% and 20%, respectively, and the exceeding rates of DEHP and DBP were respectively 35.7% and 58.3%. Conclusion The finished oil should be chosen when shopping, and bulk oil should not be stored in the non-food-grade plastic bucket as far as possible.
